Every one is different. I do 24mg/ml and hold it in my hand often, chain vapish like. But then I take little puffs, like sipping tea or so. There are so many variables. Are you a petite little lady or a Big dude for example. Were you a heavy smoker, light smoker? I thinkthat maybe lower your nic if it gets too much too often. And sometimes just set your device down for a bit. When I get a new flavor that is so delish, I can get over nic'ed myself.
